how do you allocate a single instance of a struct on the heap?  new
doesn't work, giving the error "Error: new can only create arrays or
class objects, not <structName>'s".

I know, I could allocate an array of length 1, but what I really want is
a pointer, not an array (I'm going to cast it to a void pointer soon,
and send it flying through C-space...)

struct Foo

  int b;
}

int main(char[][] argv)
{ 
  Foo* pFoo = new Foo[1];
  
  return 0;
}

You mean why can't you just do

Foo* p = new Foo; //??

I don't know. <g> new Foo[1] seems
pretty much the same to me.  It 
creates a block of heap memory
large enough to hold one Foo.
